I've never made out with a guy before and my boyfriend wants to, he has a lot of experience. Tips please?

So my boyfriend and I have done the soft gentle kiss thing, but he told me he wants to make out. I am 16 and I've never made out with anyone before. He has a lot of experience and I want to make out with him but I don't want to do something that'll turn him off. Any tips? I have no idea what to do with my tongue.
